Tip the potatoes into a medium saucepan of cold water, season well with salt and bring to the boil. Once boiling, cook for 15 mins until the potatoes can be easily pierced with the tip of a knife. Drain, steam-dry for a couple of minutes, then mash with the butter and cayenne. Season to taste and leave to cool a little.

While the mash cools, tip the flour into one bowl and season well, then tip the egg into another bowl and the breadcrumbs into a third. Line a baking tray with baking parchment.

Flatten about 1 tbsp mash into an oval in the palm of your hand. Dot a bit of the chilli jam into the centre, top with a cube of cheese, then form the mash around the filling to encase it. Place on the tray and repeat with the remaining ingredients.

Coat the croquettes in the flour, then the egg and breadcrumbs, then return to the tray. Will keep, covered in the fridge, for up to a day or frozen for up to three months.

Line a second baking tray with kitchen paper. Fill a small saucepan no more than two-thirds full with oil and heat to 180C or until a cube of bread browns in 20 seconds once dropped in. Fry the croquettes in batches for 1-2 mins (or 2-3 mins from frozen) until deep golden and crisp. Drain on the kitchen-paper-lined tray, sprinkle with salt, then keep warm in a low oven while you cook the rest. Serve with extra sweet chilli jam for dipping.
